Talking to Cambridgeshire Live she said: "I'm disgusted at the amount of nos canisters at the entrance to the water works site. There's around a hundred dotted all over the place. I’m bloody furious my dog nearly swallowed one this morning I’m scared to take him down there anymore.

"Drug habits I don't care about at all. Blatant disrespect of the environment, someone's land and everyone who uses the route, I do care about.

"It's getting worse all over the town, these bloody canisters kill people and kids just think it's a joke? What's more worrying is the location they are being dropped. It indicates someone's doing this and driving!"

Legal high

The resident is right in warning people about the canisters. While possession of the canisters is not illegal, it is illegal to sell them for the purpose of getting high.

Frank , a drugs support and advice site, says that the legal high is taken through blowing up a balloon with the gas, then inhaling the gas from the balloon. The nitrous oxide gives feelings of euphoria, as well as bringing on fits of giggles and laughter — giving it's nickname of laughing gas. Some users also experience hallucinations and distortions.

The canisters are also dangerous when inhaled. Frank says that inhaling nos is "very dangerous" with a risk of falling unconscious and suffocating after taking.

Prevention

The resident said they wanted more done to fix the problem, saying: "I’m sure the people of Waterbeach have raised concerns to police but nothing is ever done and I haven’t seen any patrol cars this side of the village since I’ve lived here.

"There needs to be some sort of camera in place because it's a hotspot for fly tippers and there's broken glass everywhere. It's making walking the dogs a danger hazard!

"Even a dummy sign saying 'smile you are on camera', might deter it!"

A spokeswoman from police said that the canisters themselves were not illegal, and that littering was a matter for the council.
